java - AndroidManifest.xml 无法正确编译

Question

我遇到了 Android Manifest 文件的问题。我在网上关注一个例子，和往常一样，代码中有错误。我已经修复了所有与 Java 相关的错误，但 Android Manifest 文件中有几个我不熟悉的错误。

代码如下:

  <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.dji.FPVDemo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <uses-feature android:name="android.hardware.usb.accessory" android:required="false" />
    <uses-feature android:name="android.hardware.usb.host" android:required="false" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <uses-library android:name="com.android.future.usb.accessory" />

        <meta-data
            android:name="com.dji.sdk.API_KEY"
            android:value="" />

        <activity
            android:name=".\DJIAoaActivity"
            android:configChanges="orientation|screenSize|keyboardHidden|keyboard"
            android:screenOrientation="sensorLandscape" >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <intent-filter>
                <action android:name="android.hardware.usb.action.USB_ACCESSORY_ATTACHED" />
            </intent-filter>
        </activity>

        <activity
            android:name=".FPVActivity"
            android:label="@string/app_name" >
        </activity>

    </application>

</manifest>

这里是错误:

Error:(18, -1) Android Resource Packaging: [FPVDemo] C:\Users\Jesse\Desktop\Android-FPVDemo-Part1-master\FPVDemo\bin\AndroidManifest.xml:18: error: Error: No resource found that matches the given name (at 'label' with value '@string/app_name').

我认为错误出在 GUI 组件未正确命名的部分，但我可能是错的。我想知道你们是怎么想的。也许我错过了一些简单的东西。

检查您是否创建了strings.xml 文件，其中是否包含app_name 的键值对。或者只是尝试在标签中给出值，例如

android:label="我的应用"
